News – Hydrogen fuel cells are the way forward, according to Kia and sister company Hyundai

A state of the art Hyundai fuel cell vehicle showing the way forward…

Fuel for thought, after nearly 180 years.

The fuel cell is the only technology which will provide a sustainable automotive industry in the long run, according to the head of research for Kia Motors FCEV (Fuel Cell Electric Vehicles)team, Dr Saehoon Kim (pictured below).

The Korean manufacturer is the country’s oldest vehicle maker and is pouring millions of dollars into research to develop the models of the future, notably using its advanced fuel cell – first invented in 1839 by a Swansea-born scientist – in order to reduce cost and make it affordable for motorists.

He says the automotive industry is facing a real struggle to cut exhaust emissions to levels demanded by politicians and governments around the world and it’s going to become progressively harder to meet legislation.

Dr Kim said it is Kia’s, and sister company Hyundai’s, view that current battery technology will be unable to meet the needs of motorists in future when legislation will virtually outlaw the internal combustion engine. “Batteries have an issue over their range and recharging,” he said. “This will make them unsuitable for anything other than comparatively short distances but a fuel cell electric vehicle will have a range and performance broadly similar to petrol and diesel engines of today and its refuelling will take about the same time as we are used to now.”

Dr Kim was speaking during a visit to Kia’s advanced engineering centre in Mabuk near Seoul, where he heads hundreds of engineers looking at future powertrains, technologies and systems and who work with car designers shaping the models of the future.

“The real advances for the FCEV will be in trucks and buses using them because they have higher demands on load and distance which cannot be matched by big-battery power and as the lessons and costs of developing these feeds into the industry it will become more affordable for the cars of tomorrow. That’s why we are getting lots of requests from logistics companies to provide trucks with fuel cells.”

The outspoken engineer said some car makers were considerably ahead of rivals because they had looked at electric vehicles and developed them as hybrids over two decades ago but even these were likely to be overtaken by the hydrogen fuel cell models now being developed.

Hydrogen is the most plentiful product in the universe and can be found in abundance, which will make it much cheaper than generating electricity alone to power cars, trains, boats or through rival fossil fuels. Importantly, it is not subject to any supply issues due to political or production interests in the way of oil, gas or coal products.

Dr Kim said it requires the will of scientists, engineers, politicians and business to embrace hydrogen as the future fuel because its supplies are limitless and best of all it does not produce any harmful emissions from a fuel cell.

He is confident that the known weakness of FCEVs, the “furring up” of cell plates over comparatively short periods of typically four years will be overcome very soon. This issue currently means fuel cell efficiency gradually degrades and involves a costly replacement but he sees a time coming when the contamination will be addressed and a replacement cell stack is fitted in a routine major service, much like vehicles undergo now, and at a reasonable cost.

Another issue of the water system freezing in cold weather and needing thawing out is being addressed and he believes is very close to being solved for drivers in more extreme locations. They have run tests to get FCEVs starting within 30 secs in minus 30 Deg C temperature and instantly at minus 10 Deg C.

Dr Kim said all the progress being made in research centres such as Kia depended on a comprehensive infrastructure to deliver hydrogen to its users and he believes this will be built initially around the demands of long distance operators such as fleets.

The rise in numbers of plug-in electric vehicles and pure electric vehicles over coming years will put increased demands on providers to install charging points at homes, businesses, filling stations, shopping centres and other locations. The combined amount of electricity required will put incredible pressure on Governments to build nuclear power plants to generate what is needed and the cost and political will is not assured and raises the issue of physical and national security.

Other components used in electric battery vehicles have finite problems and this could leave them open to political or market forces, he added.

“When we first developed a FCEV towards the end of the last century we described it as the million dollar car because of the costly components, but these have over time come down and I think we are much closer to calling the next models the $100,000 cars, and who knows what figure it will fall to in the future?”

That first model was a Santa Fe which led to the Tucson and then the ix35 FCEV for the Hyundai sister company which rolled off the Ulsan, South Korea line in 2013, but produced in limited numbers because of the cost and market.

“We are certainly moving closer to the price of today’s better ICE (internal combustion engine) cars and looking ahead I believe a future FCEV will be cheaper than a battery car,” he said.

How the Kia/Hyundai fuel cell system operates.

It could happen sooner than many think as cities and governments tighten emissions regulations and Dr Kim believes we will routinely see some form of FCEV power unit in cars inside ten years to comply with laws.

For the immediate future he believes car makers will move into wider adoption of hybrid technology which uses a small ICE in conjunction with an on-board battery and charger pack, but they will also offer pure battery as well as FCEVs.

Looking further ahead the ICE is expected to disappear and more fuel cell models will be added to ranges as the technology improves and refuelling stations are expanded with costs dropping as well. Hydrogen is the fuel source of the future and it’s around the corner, believes Dr Kim.
